C Programming Lab

C Programming Lab is a practical, lightweight C code editor and native compiler built for Android. It lets you write, compile, and run real C code directly on your phone or tablet—completely offline, without needing an internet connection or a remote server. Whether you are studying for college computer science exams, practicing coding problems, or just testing out an idea on the go, C Programming Lab gives you everything you need in a clean, distraction-free environment. KEY FEATURES • 100% Offline C Compiler Compile and execute your programs right on your device. Execution is fast and happens entirely locally, so you don't have to wait on cloud servers or worry about internet access. • Practical Code Editor Built for Mobile Writing code on a touchscreen can be frustrating, so we built tools to make it easier: - Quick symbol row right above your keyboard for instant access to { }, ( ), [ ], ;, :, #, <, >, and & - Clean syntax highlighting that makes code easy to read - Line numbers and auto-indentation - In-editor search and replace to quickly find variables and functions - Undo and redo support - Adjustable text sizing and full support for both Dark Mode and Light Mode • Interactive Terminal with Stdin Unlike simple script runners, C Programming Lab gives you a real interactive console: - Full support for scanf() and user input while your program runs - Formatted output showing stdout, stderr, and execution time in milliseconds - Clear exit codes (code 0, errors, timeouts) - One-tap button to copy terminal output to your clipboard • Built-In Practice Templates Get started immediately without typing boilerplate code. The app includes ready-to-run templates covering: - Hello World basics - User input and arithmetic with scanf() - Pointers, memory addresses, and variable swapping - Loops, arrays, and standard functions • Secure & Private Your source code belongs to you. All files and programs are stored locally in your device's private app directory. The app doesn't upload your code anywhere, doesn't require an account or login, and doesn't ask for unnecessary permissions. If you are learning C or need a reliable compiler in your pocket, give C Programming Lab a try!
